Fitting the ONErack dual-redundant PSU
To avoid damaging your ONErack, build it in a clean, tidy area.
This installation guide assumes you have already built a ONErack
chassis.
Read more about building a chassis in the installation guide for the
ONErack chassis. The guide is available from the Downloads tab at
tvone.com/onerack.
Airflow
You can place the dual-redundant PSU anywhere in your ONErack
chassis. If you mount the dual-redundant PSU at the left-hand end,
leave an empty numbered hole at the left-hand end. If you mount the
dual-redundant PSU at the right-hand end, leave an empty numbered
hole at the right hand end. Leaving an empty numbered hole allows
space for airflow.
1. Clip a pair of guide rails into the lower and upper mounting rails.
nUse the numbers on the mounting rails, and the included
template, to help you fit the guide rails straight and in line
with one another.
nLeave 16 numbered holes between each pair of guide rails.
nMake sure the groove is on the right when you look from the
front of the chassis.

2. Slide the dual-redundant PSU into the groove in the guide rails.
3. Screw the top and bottom of the dual-redundant PSU in place
with 4 M3 screws.
4. OPTIONAL: Connect one or both daisy-chain cables to the rear of
the dual-redundant PSU, ready for your modules.
You only need to connect a daisy-chain cable to the upper port if
you need to provide 350 W to the lower rail, or if you intend to
create an upper rail with extra voltage selectors, sold separately.
Ask your sales representative about 1RK-XTRA-RAIL and
1RK-XTRA-PWR.
5. When you have connected all your modules with daisy-chain
cables, connect your dual-redundant PSU to two electrical
outlets.
The green LEDs on the front of the dual-redundant PSU light up.
Read more in the guide for ONErack modules. The guide is
available from the Downloads tab at tvone.com/onerack.
